Plan Your Perfect
Race Simulation
Physics-based race simulation with metabolic modeling. Know your exact power strategy, nutrition needs, and finish time before you start.
While competitors ask you to guess your parameters, our Simulation uses YOUR tested values from Powertest and Aerotest for unmatched accuracy.
700+ race courses worldwide • Used by coaches & pro athletes
"Whether it's a time trial for men or women, the simulation software helps us achieve the best possible times for our riders. The precision and real-time data are game-changers for race preparation."
Don't Race Blind

Different Ways to Predict Your Race
Compare race prediction approaches and find what fits your goals.
| What Can You Plan? | Metabolic Simulation | Power-based Prediction |
|---|---|---|
| Race Time Prediction | Physics + your metabolism | Physics + your FTP |
| Based On | VO2max, VLamax, and FTP | FTP and power curve |
| Nutrition Planning | Carbs and fat burned per segment | Different focus |
| Weather Conditions | Wind per segment | Wind modeling |
| Equipment Comparison | Compare setups side by side | Equipment optimizer |
| Pacing Strategy | Based on your energy systems | Based on power targets |
| Course Details | Elevation, curves, segments | Elevation and segments |
| Best For | Athletes who want nutrition and metabolism insights | Athletes focused on power-based pacing |
Both approaches help you race faster. Choose based on your planning needs.
The key difference: know exactly how many carbs you will burn, not just your finish time.
